RADIATOR-VALVE DEVICE.

SPECIFICATION forming part of Letters Patent No. 479,400, dated July 26,1892.

Application filed April 21, 1891.

To aZZ whom it may concern:

Be it known that 1, JOHN COLLIS, a citizen of the United States,residing at Des Moines, in the county of Polk and State of Iowa, haveinvented a new and useful Improvement in Radiator-Valve Devices, ofwhich the following is a specification.

My invention relates to an improvement in the class of valve devicesemployed at the radiators of steam-heating systems to enable cutting offthe supply of steam at any radiator provided with the device withoutthereby obstructing the circulation in the steampipes. As the valvedevice in the class referred to has hitherto been constructed, whileprovision is made that by turning the valve to shut off the steam-supplyto the radiator there shall be a short circuit produced for the steambetween its inlet and outlet pipes outside the radiator, theconstruction is such as to close the short circuit when the valve isturned to open the radiator to the steam-sup ply. This construction hasthe disadvantage I that it affords no means for enabling the condensedsteam in the supply to separate therefrom, but requires it to be carriedin the supply to the return-pipe through the radiator, wherein much ofthe condensation is liable to be lodged.

My object is to provide a construction of valve device in the aforesaidclass whereby there shall always be an opening in the passage betweenthe steam inlet and return pipes whether the valve shall be closed toshut ofi the supply to the radiator or open to admit it thereto. Thuswhen the valve is open I am enabled to provide for separation from thesteam-supply before it enters the radiator of the condensation, which isshort-circuited into the return-pipe, and thereby the radiator issupplied with the more-dry steam.

My improvement not only permits the circulation to continueunobstructedly through the pipe system in case of closing any number ofthe radiator-valves in the steam-circuit, but it particularly adapts thesteampipes to be laid horizontally throughout the building behind thebase-boards of the walls, and the valve-containing branch pipestherefrom to the radiators to be short, according to the short distanceof the radiators from the walls, by leading by the most direct course$eria1No. 389,801. (No model.)

into the radiators. The pipes may also be laid in front of thebase-board and the connections made with elbows or swing-joints, and allpossible expansion of the supply and waste pipesmay be looked afterwithout raising the radiator-feet from the floor.

In the accompanying drawings, Figure 1 is a view in broken sideelevation representing a loop radiator in operative position with myimproved valve device in place in the steamcirculating system of thekind involving supply and return pipes. Fig. 2 is a section taken on theline 2 of Fig. 1 and viewed in the vdirection of the arrows. .Fig. 3 isa View showing my improved valve device in elevation as connected in acirculating system having a single pipe for both the supply to andexhaust from the radiators. Fig. i is an enlarged vertical sectionalview of the valve, taken on the line i of Fig. 3 and viewed in thedirection of the arrow. Fig. 5 is a similar view of the same, taken onthe line 5 of Fig. 1 and viewed in the direction of the arrow. Fig. 6 isa plan sectional view of the same, taken on the line 6 of Fig. 3 andviewed in the direction of the arrow.

A is my improved valve device of the socalled corner-valve variety, andthe construction of which renders it a three-way gate-valve. It involvesthe following described details in its construction: The shell 0, whichshould be of the general cylindrical form illustrated,is provided nearits base with an opening q, the diameter of which is preferably aboutthree-quarters of an inch, and over the opening q with a somewhat-largeropening 19, both said openings having nipple extensions, as shown, atwhich to connect the pipes, as hereinafter described. Near the base ofthe shell 4" at a right-angle to the opening q is an opening 0, havingcast in it a short tube 0', adapted to be connected at its outer endwith the inlet-opening to a radiator B, and projecting at its oppositeend into the shell, where it alfords a valve-seat n. Centrally behindthe valve-seat n in the shell 0" is a vertical web on, inclining fromits upper end toward the base of the opening 0, and affording a guidefor the valve 0. The pre ferred form of the valve 0 is that of a blockhaving a straight flat face provided with a circular seat Z for apacking-ring Z, and tapering in a downward direction at its rear side,as shown at a: in Fig. 4, to conform to the opposite taper of the rib m,which fits into a longitudinal recess Z Fig. 6, in the back of thevalve. When the valve 0 is in its closed position, (illustrated,) thepacking ringl bears against the seat n.- For raising and lowering thevalve 0,1 provide a rotary threaded stem 0, engaging a correspondinghole in the valve, and provided with a collar 70, seated in a recess ina head 2', screwed into the upper end of the shell, an internally andexternally threaded ring 1; being screwed into the shell upon the headand aifording a bearing for the threaded end of the head h, whichconfines the stem 0 at its collar against longitudinal movement andthrough which the stem passes, being surrounded at the outer end of thehead it with a suitable stutfing-box g.

With steam supply and return pipes f and e, arranged as shown in Figs. 1and 2, my improved device A is applied by connecting it at its opening 0with the radiator B, and by branch pipes f and 6, respectively, with thepipes f and e. If, as indicated in Fig. 3, only a steam-pipe f beprovided both for the supply to and exhaust from the radiator, bothbranch pipes f and e may be connected with it, as represented.

When the valve 0 is raised, and thus removed from its seat n, to openthe passage 0, the steam, which is always free to enter the valve deviceA at its opening 19, may pass into the radiator by way of the opening 0,and the condensation may pass out at the lowermost openingq into thepipe e,if provided, or into the pipe f if only the latter be provided.Lowering the valve C to the position of covering the seat n eltectnallyprevents steam entering the chamber of the device A at the inlet 1) fromgaining access to the radiator, but does not interfere with thesteam-circulation through the valve device from the inlet p to theoutlet q, since the latter is always accessible along the sides of thevalve 0, which does not diametrically fill the shell 0'.

It will thus be quite apparent that'shutting off the steam-supply to aradiator or to any number of radiators in a steam-heating system notonly does not afiect the steam-circulation but does not necessitateconducting the condensation into the radiator, because the directly intothe branch passage for the steam from the inlet to the outlet opening ofeach valve device A is not thereby closed.

The lower opening q may be provided in the base of the shell withadvantage, particularly where a radiator is in the center of a room oraround a column.

WVhat I claim as new, and desire to secure by Letters Patent, is- 1 1.In a radiator-valve device, a shell having an outlet-opening at which toconnect the device with aradiator and a supply-opening and adischarge-openin g in vertical line with each other to one side of theoutlet-opening at which to connect the device with the circulatingpipesystem, said supply and discharge openings having permanent opencommunication with each other in the shell past the said outlet-opening,in combination with a verticallyadjusta-ble valve confined in the shellwith relation to its outlet-opening and provided with means foroperating it to open and close the said opening, substantially asdescribed.

2. A three-way-valve device for use with a radiator and itscirculating-pipe system, comprising a shell having an outlet-opening 0,a a

tube cast therein adapted to be connected at its outer end with theinlet-opening of a radiator and projecting at its other end within theshell to form a valve-seat n, a supplyopening 19 and a discharge-openingq, respectively, above and below the plane of the outletopening to oneside of the latter and having branches f and 2' connecting them with thecirculating-pipe system, and a vertically-adjustable valve C, confinedin the shell with relation to the said outlet-opening and provided withmeans for raising and lowering it to open and close the openingo, theopenings 19 and q having permanent direct communication with each other,whereby when the valve is closed the circulation is continued betweenthe said branches and whereby when the valve is open condensation in thesteamsupply from the branch pipe f discharges pipe e, substantially asdescribed.
